No worries, I could not think of anything better. But maybe someone already modelled such a phenomenon and has a trick for it.

Yes that is also the idea I had, I just figured there would be a proper way to do it without having to play with the geometry parameters. But I will be working on solving it this way, meanwhile if...

It would be a laplacian problem if the entire fluid region in the reservoir was at constant temperature, but that is not what happens in theory. There will be a temperature gradient around the...

To clear any misunderstanding, I drew the dashed line only to symbolize the junction, like I said there is no discontinuity, no physical boundary.

I attached a basic drawing of the problem. There is no flow involved, only the stationary fluid. I am getting the temperature profile from which I compute the heat flux. The problem is simple in...

Hi, thank you for your reply.
Yes I am indeed solving for temperature, but I said the reservoir was kept at constant temperature T=2.17K, however at the "junction", meaning the area where the...

Fluid channel connected to "infinite" reservoir

Dear Foamers,

I am trying to solve the temperature distribution in liquid helium. One part of the fluid is contained in a narrow channel, one end of the channel is a dirichlet condition with a...
